Water spraying out from inside the heater ??
Do you mean spraying out thru the drain valve ?

Those drain valves are replaceable but it normally requires draining the tank although I have changed therm working quickly when some water sloshing won't cause any damage. You MUST turn the WH off and allow the water to cool off before attempting any replacement.

You can replace the plastic valve with a brass one designed for water heaters or use a short 3/4" brass nipple and a 3/4" threaded ball valve.

THIS would be a brass water heater direct replacement type valve. Just one of many brass ones available.

Water heater was off for days ,along with water pressure to it ..when pressure was back on ,it popped something down there at drain causing spray an gravity took over till I emptied it.
An yes I had to drain it ,no choice with it spraying out from inside the area behind the base,of the drain spickett, area where it connects into heater.main water off -.I just need to see if that piece was leaking where it connects..or why it was spraying out .

Yes, the first step is for YOU to look for where the leak is located. If the leak is coming from inside the water heater body then you probably need a new heater. If it is leaking from the drain valve that can be easily replaced.

You can see what you flush out no matter what the valve is made of. Most water heaters come with a plastic valve but you can install brass if you want.

"an what psi should i be getting to it?"
I don't understand your question? You are not applying pressure to anything. When you open the drain valve water is forced out just like a spigot inside the house.

Ok, what's that supposed to mean "Heating elements..not the crud"??? Are you asking if you should remove your heating elements and inspect them?

Your water heater does not affect the water pressure and there is no pressure adjustment on your water heater. The water pressure is determined by the water pressure in your home.

Water flows downhill.

The water heater drain valve is probably the lowest point in the entire water system within your house.

So after the main water supply is shut off, all the water in the hot water pipes upstairs has to come down as well as the water in the heater tank having to drain out.

Or you could say that water still in the water heater tank imparts a positive PSI at the level of the drain valve owing to its weight.

After you have finished the project and the water is turned back on, calculating the difference in PSI on the second floor versus in the basement will be left as an exercise.

You should see water gushing from a hot faucet upstairs for a full minute before turning the water heater heat back on.

A plastic drain valve is a sign of a cheapy water heater. My new Bradford-White water heater had a brass ball valve drain.
